Not everyone uses the same operating system and why should they? Tiled supports Windows, Mac, and Linux so you can work in any environment you like. Also with daily builds you get to stay ahead of the curve!
It’s not a huge deal but you do need to implement Tiled into your engine if you don’t have it. Dont be lazy just follow this guideline (https://github.com/bjorn/tiled/wiki/TMX-Map-Format) to get your game running.Must implement .tmx if your engine doesn’t support Tiled.
If you open up a new game and check the checkbox that copies the default assets it will create an error due to the default Battle System. You will have to create your own Battle System to get around this.
